For battery protection during OTG mode, the device monitors the battery temperature to be within the VBCOLD to VBHOT thresholds. When RT1 is 5.24 KΩ and RT2 is 31.31 KΩ, TBCOLD default is -10°C and TBHOT default is 60°C. When the temperature is outside of this range, OTG mode is suspended, the converter stops switching. The charger waits in OTG mode (EN_OTG = 1). In addition, the VBUS_STAT bits are set to 000 and the corresponding TS_COLD_STAT or TS_HOT_STAT is reported. Once temperature returns to the normal temperature range, OTG mode is recovered and TS stauts bit is cleared. During TS fault, REGN still stays on.
